| 20090146668 | ANTI-PINCH SENSOR AND EVALUATION CIRCUIT - An anti-pinch sensor is provided for detecting an obstacle in the path of a regulating element of a motor vehicle, the sensor can include a sensor body, a first measuring electrode that can be arranged in the sensor body and can be used to produce a first outer electrical field in relation to a counter-electrode, and an electrically separated second measuring electrode that can be arranged adjacent to the first measuring electrode in the sensor body and can be used to produce a second outer electrical field in relation to the counter electrode. The measuring electrodes can be formed in such a way that the first outer electrical field has a larger range than the second outer electrical field. An evaluation circuit is also provided that is suitable for evaluating an anti-pinch sensor. The detection reliability of such a clamping sensor is not affected by dirt or water on a surface thereof. | 06-11-2009 |

| 20100072933 | METHOD AND DEVICE FOR DETECTING THE ROTATION OF A BRUSH-OPERATED D.C. MOTOR - a method and a device for detecting the rotation of a brush-operated d.c. motor comprising a number of winding branches which are electrically connected between brushes, during the operation of the motor, by means of plates, according to the rotational angle. According to the invention, an alternating voltage signal is modulated on the basis of a supply direct voltage for the brushes, by which means the course of the complex resistance of the direct current motor is determined and used for the detection of rotation. In this way, the invention enables a cost-effective rotation detection that can be used in motor vehicle technology without requiring additional mechanical components. | 03-25-2010 |
| 20100231023 | ADJUSTING DEVICE FOR A HEADREST OF A MOTOR VEHICLE SEAT - An adjusting device for a headrest of a motor vehicle seat is specified. The adjusting device comprises, in a first variant, a capacitive proximity sensor integrated into or designed for integration into the headrest having at least three transmitting electrodes spaced apart vertically from one another and having a common receiving electrode. In a second variant of the adjusting device, the proximity sensor has at least at least three receiving electrodes spaced apart vertically from one another and has a common transmitting electrode. In both variants, the adjusting device also has an actuating drive for motorized vertical adjustment of the headrest relative to the vehicle seat, as well as a control unit. The control unit here is designed to drive the transmitting electrodes or transmitting electrode for emission of an alternating electric field to determine from the received electrical signals detected from the receiving electrode or the receiving electrodes, respective associated measured capacitance values that contain information about the capacitance produced between each of the transmitting electrodes or receiving electrodes and the common receiving electrode or transmitting electrode, and to drive the actuating drive to establish a vertical target position of the headrest relative to the head position of a vehicle occupant as a function of the measured capacitance values. | 09-16-2010 |
